Functional description
7.1 Function selection
[1]
[2]
Signal levels on D
+
/D
are determined by other USB devices and external pull-up/down resistors.
In ‘suspend’ mode (SUSPND = HIGH) the differential receiver is inactive and output RCV is always
LOW. Out-of-suspend (‘K’) signalling is detected via the single-ended receivers VP and VM.
During suspend, the slew-rate control circuit of low-speed operation is disabled. The D
+
/D
are still
driven to their intended states, without slew-rate control. This is permitted because driving during
suspend is used to signal remote wakeup by driving a ‘K’ signal (one transition from idle to ‘K’ state)
for a period of 1 to 15 ms.
